In 1999, the war in Kosova caused much suffering to innocent civilians, especially women and children. Grieved by the inhumane act of ethnic cleansing unleashed by the minority Serbs, Datuk Dr. Jemilah Mahmood, an obstetrics-gynaecologist offered her medical services voluntarily. However, she faced much difficulty in getting the needed support from already established organisations. Thus, she and a few like-minded individuals established the Malaysian Medical Relief Society, better known as MERCY Malaysia in June 1999.

Dr. Jemilah then led the first aid mission to Kosova, which was followed by four consecutive missions. The teams made up of Malaysian medical professionals braved the uncertainty of a war torn country to offer a helping hand, love and care, from thousands of miles away. They knew little about what to expect but their passion to help heal the wounds of the innocent fuelled their determination. Their compassion was a true sign of inner strength and courage. The people they served were their inspiration. Although MERCY Malaysia began as a medical relief society, volunteers from other fields and backgrounds soon became a part of the society.
